FMAX(3) | Library Functions Manual | FMAX(3)

# NAME

fmax, fmaxf, fmaxl, fmin, fminf, fminl — floating-point maximum and minimum functions

# LIBRARY

Math Library (libm, -lm)

# SYNOPSIS

#include <math.h>

double
fmax(double x, double y);

float
fmaxf(float x, float y);

long double
fmaxl(long double x, long double y);

double
fmin(double x, double y);

float
fminf(float x, float y);

long double
fminl(long double x, long double y);

# DESCRIPTION

The fmax(), fmaxf(), and fmaxl() functions return the larger of x and y, and likewise, the fmin(), fminf(), and fminl() functions return the smaller of x and y. They treat `+0.0` as being larger than `-0.0`. If one argument is an NaN, then the other argument is returned. If both arguments are NaNs, then the result is an NaN. These routines do not raise any floating-point exceptions.

# SEE ALSO

fabs(3), fdim(3), math(3)

# STANDARDS

The fmax(), fmaxf(), fmaxl(), fmin(), fminf(), and fminl() functions conform to ISO/IEC 9899:1999 (“ISO C99”).

# HISTORY

These routines first appeared in FreeBSD 5.3 and NetBSD 5.1.
